Shore excursions - Mirabella Catamaran on St. Marteen and St. John snorkel are a must!!!

The waterslides - Really fun!

The negatives:

Pool area is too small for 3000+ guests!

Atlantis water park shore excursion - This was expensive, not planned well, and NOT worth the money! Getting there was difficult! Not to mention that there was not enough time once you arrived. More
Lines were long, food was expensive - Yuck!!! Do yourself a favor; if you want water slides, stay on the ship!!!

Overall:

I would definitely sail NCL again! The ship, crew, food, and destinations were great! Just do yourself a favor and don't bother with the waterpark at Atlantis! Try just the tour or the dolphin experience if you go at all. Much better bang for your buck! Less
